About this Water
- Freestone
- Best months: May–Oct, peak June–Aug
The Logan River in northern Utah's Cache Valley is a classic mountain freestone — small, cold, and intimate, running through Logan Canyon east of Logan. Native Bonneville cutthroat trout hold the upper canyon; browns and rainbows dominate the middle and lower river. The river is wadeable throughout with easy roadside access along Highway 89. Hatch sequences are reliable: stoneflies in early summer, caddis through July, and terrestrial fishing through August and September. The upper canyon stretches above First through Third Dam offer the most native cutthroat opportunity.
The Logan holds one of the strongest remaining native Bonneville cutthroat populations — a subspecies once thought near extinction, now recovering thanks to dedicated Utah DWR conservation efforts.
